摘要：

Polypropylene (PP)/wood-fiber (WF) composites were prepared by intermeshing co-rotating twin screw extruder, and microcellular closed cell PP/WF composite foams were prepared by using pressure-quenched batch process method. The effect of various compatibilizers on the mechanical properties, morphology, crystallinity, rheological properties, and foamability of PP/WF composites were investigated. The results showed that PP/WF composite with addition of PP-g-MA as compatibilizer had the highest tensile strength, stiffness, and crystallinity, after foaming, it showed highest relative density and cell density, as well as the smallest cell size. Higher crystallinity of PP/WF composites, showed higher stiffness and higher relative density. (c) 2013 Society of Plastics Engineers
